I don't get it either with both switching and being bi. For those who think a person can only be one or the other, I think they're closed minded, and in some cases they are that themselves, see something wrong with it and/or don't want anyone to know and don't know how to deal. For those who are bisexual and are a switch, it works. It does depend on the person they're with, the situation and even the mood. At least that's what I've gathered from what I've seen with friend and family. If I ever get fully into BDSM with my bf, we'd be a switch couple. Even now with light play in the bedroom, one day it's my turn, the next day it's his.
